Geological Survey of Finland, Espoo, Finland, 159 pp. ISBN 978-952-217-201-3 Geological Survey of Finland Espoo 2012 4 Preface This Abstract Volume contains seventy four abstracts submitted to the Supercontinent 2012 Symposium to be held during Sept. 25-28, 2012 at the Kumpula Campus of the University of Helsinki, Finland (http://supercontinent2012.helsinki.fi/). The four days symposium focuses on current knowledge and problems regarding supercontinent research with a focus on the Precambrian era. Some seventy geoscientists from around the world will arrive in Helsinki to discuss the recent developments and problems in the research of supercontinents, their assemblies and break-ups and to raise new ideas. The Symposium will be preceded by an Excursion through seven geological landmark sites in Finland. Twenty seven scientists will participate in the excursion. This Volume is edited by Satu Mertanen, Lauri J. Pesonen, Pathamawan Sangchan and Ella Koljonen. We thank Kari Jääskeläinen, Tuire Laine, Robert Klein, Tommi Vuorinen, Johanna Salminen and Toni Veikkolainen for their help in preparing this Volume and the Symposium. The publishing of the Abstract Volume was made possible with the help of the Geological Survey of Finland. The symposium would not be possible without the help of scholarships by the Finnish Cultural Foundation, the Finnish Academy of Science and Letters, the Finnish Society of Sciences and Letters and financial and logistic support by cities and towns of Helsinki, Keuruu, Lappajärvi, Rovaniemi and Tervola. We also thank Keijo Hämäläinen, Kaarlo Hämeri, Tuulikki Pitkänen, Anu Palo and Pirjo Käyhkö for their help in organising the Symposium.

Foreword and Acknowledgements The following thesis was written over the course of 5 years, starting in August 2013, in the framework of the joint GEUS-MMR “SEGMENT (South-East Greenland Mineral Endowment Task)”-project. During the course of this study, I had the opportunity to witness the beautiful scenery and outstanding geology of Greenland firsthand during a one-month fieldtrip to the area around Tasiilaq in June and August of 2014, for which I greatly appreciate funding by the Geological Survey of Denmark and Greenland (GEUS) and the Ministry of Mineral Resources of Greenland (MMR). Regular funding was provided by the Deutsche Forschungsgemeinschaft from 2013 to 2016, with additional funding until late 2017 by employment at the Institute of Applied Mineralogy and Economic Geology at RWTH Aachen. At first, I want to thank my supervisor Annika Dziggel for her great support and guidance, but also for initiating this interesting project in the first place. Thank you for your support during fieldwork, for encouraging me to keep a sharp mind during analysis and interpretation and for teaching me how to properly present my data. Many thanks also go out to my Co-Supervisor Sven Sindern for his support during the countless hours I spent in the laboratory, as well as with the whole-rock data and isotopic dating.

  • Paleomagnetism and U-Pb Geochronology of the Late Cretaceous Chisulryoung Volcanic Formation, Korea
    Jeong et al. Earth, Planets and Space (2015) 67:66 DOI 10.1186/s40623-015-0242-y FULL PAPER Open Access Paleomagnetism and U-Pb geochronology of the late Cretaceous Chisulryoung Volcanic Formation, Korea: tectonic evolution of the Korean Peninsula Doohee Jeong1, Yongjae Yu1*, Seong-Jae Doh2, Dongwoo Suk3 and Jeongmin Kim4 Abstract Late Cretaceous Chisulryoung Volcanic Formation (CVF) in southeastern Korea contains four ash-flow ignimbrite units (A1, A2, A3, and A4) and three intervening volcano-sedimentary layers (S1, S2, and S3). Reliable U-Pb ages obtained for zircons from the base and top of the CVF were 72.8 ± 1.7 Ma and 67.7 ± 2.1 Ma, respectively. Paleomagnetic analysis on pyroclastic units yielded mean magnetic directions and virtual geomagnetic poles (VGPs) as D/I = 19.1°/49.2° (α95 =4.2°,k = 76.5) and VGP = 73.1°N/232.1°E (A95 =3.7°,N =3)forA1,D/I = 24.9°/52.9° (α95 =5.9°,k =61.7)and VGP = 69.4°N/217.3°E (A95 =5.6°,N=11) for A3, and D/I = 10.9°/50.1° (α95 =5.6°,k = 38.6) and VGP = 79.8°N/ 242.4°E (A95 =5.0°,N = 18) for A4. Our best estimates of the paleopoles for A1, A3, and A4 are in remarkable agreement with the reference apparent polar wander path of China in late Cretaceous to early Paleogene, confirming that Korea has been rigidly attached to China (by implication to Eurasia) at least since the Cretaceous. The compiled paleomagnetic data of the Korean Peninsula suggest that the mode of clockwise rotations weakened since the mid-Jurassic.

Received: 27 May 2018; Accepted: 30 July 2018; Published: 3 August 2018 Abstract: Zircon U–Pb dating and Hf isotopic analyses are performed on clastic rocks, sedimentary tuff of the Dongchuan Group (DCG), and a diabase, which is an intrusive body from the base of DCG in the SW Yangtze Block. The results provide new constraints on the Precambrian basement and the Late Paleoproterozoic to Mesoproterozoic tectonic evolution of the SW Yangtze Block, South China. DCG has been divided into four formations from the bottom to the top: Yinmin, Luoxue, Heishan, and Qinglongshan. The Yinmin Formation, which represents the oldest rock unit of DCG, was intruded by a diabase dyke. The oldest zircon age of the clastic rocks from the Yinmin Formation is 3654 Ma, with "Hf(t) of −3.1 and a two-stage modeled age of 4081 Ma. Another zircon exhibits an age of 2406 Ma, with "Hf(t) of −20.1 and a two-stage modeled age of 4152 Ma.

Sillman Penn State University This work is licensed under a Creative Commons Attribution‐Noncommercial‐No Derivative Works 3.0 license. It may be distributed and shared, with attribution, but not altered or used commercially in any way. “Where Is (and Was) Pennsylvania?” Pennsylvania is a pretty obvious place to us. It’s a rectangular, politically defined piece of the eastern United States with a wiggly eastern border that follows the Delaware River and three, very straight other borders on the north, west, and south that were laboriously marked off after a great deal of social and legal travail and even some violence. It’s a hilly to mountainous, river‐rich place with forests and fields and cities. Its statistics are simple: it is about three hundred miles from east to west and a little less than one hundred and seventy miles from south to north. It comprises 46,058 square miles (although the number “45,308” shows up in some references). Its latitude range is thirty‐nine degrees forty‐three minutes N to forty‐two degrees N, and its longitude range is seventy‐four degrees and forty‐three minutes W to eighty degrees thirty‐one minutes W (Netstate 2008). This Pennsylvania, though, hasn’t always been all of that. The great rectangle of Pennsylvania has been, through the geological history of the Earth, in the southern hemisphere, on the equator, and in a great many places in between. It has been oriented with its long, three hundred mile axis east to west and also with this long axis running south to north.

    Precambrian Research, 64 (1993) 295-309 295 Elsevier Science Publishers B.V., Amsterdam The late Svecofennian granite-migmatite zone of southern Finland—a belt of transpressive deformation and granite emplacement Carl Ehlers*, Alf Lindroos and Olavi Selonen Department of Geology and Mineralogy, Abo Akademi University, SF-20500 Abo, Finland Received March 21, 1991; revised version accepted November 3,1992 ABSTRACT The late Svecofennian granite-migmatite (LSGM) zone in southwestern Finland is a ~ 100 km wide and 500 km long belt transecting the southern Svecofennides from WSW to ENE. It was formed in an area of thin pillow lavas, volcaniclastic sediments and limestones. The area is interpreted as having been an early basin of crustal extension which was the locus of an inherited zone of weakness in the Proterozoic crust. Early recumbent folding was followed by crustal thickening and intrusions of ~ 1.89-1.8 8 Ga old plutonics. The LSGM-zone is characterized by 1.84-1.83 Ga old rhomboidal sheets of late Svecofennian microcline granite and is bounded by ductile shears. Amongst the two major phases of deformation defined in the LSGM-zone, the earlier one (Dl) affected only the supracmstals and the 1.89-1.88 Ga old early plutonics. In contrast, the later phase (D2) also deformed the late Svecofennian migmatites and granites. Dl represents a complex and long-lasting deformation event which in- cluded overturning and thrusting of the Svecofennian strata. D2 comprised ENE-WSW directed drag accompanied by NNW-SSE compression. The Svecofennian crust was thick- ened further and anatectic microcline granites intruded along thrusts.
